RegulationofSplicingthroughSam68
While transcriptional regulation is often viewed as the most prevalent way extracellular signals to regulate gene expression, post-transcriptional regulation of splicing, RNA stability, and translation are also regulated by extracellular signals. Sam68, a member of a family of RNA-binding proteins called STAR proteins, mediates alternative splicing in response to extracellular signals, such as altered splicing of CD4......阅读全文
